(01. 22 903 "This invention relates to botto'm 'bdardsfor molds, and more particularly, has reference toa" mold bottom board construction including means attachedthereto for facilitat' gthe movementof Y I p boardcohstruction, otherthan one which will e a achmen o s tsl' ii.

the charactentobe described hereinafter, and

a moldlfrom .one location to other. l Byf wayfofbackground, 'it'ma In noted. hatfin the handling of'molds, 'it' is desirable that the movement thereof from location to location be facilitated. At present, there is not in use so far as I am aware, such a means, and an important object of the present invention is, accordingly, to provide a bottom board construction that will speed up greatly the handling of molds.

It is a purpose, additionally, to provide a means of the character described including a roller mounting for the bottom boards, whereby the molds can be placed upon a mold track or conveyor line, or can be moved out upon the floor, as is often desirable, with speed and ease.

Another important object is to provide a roller mounting for bottom boards which will make possible a very inexpensive mold conveyor line which will find application in small plants as well as in large ones.

Another important object is to provide a roller mounting of the character stated which will have all the advantages of facilitating movement of the molds, but which will not in any way place limitation upon the number and kind of jobs to be handled.

Another important object is to provide a roller mounting for bottom boards which will nevertheless permit mold storage in minimum space, and in such a way that the rollers will not interfere with said storage.

With the foregoing and other objects in view which will appear as the description proceeds, the invention consists of certain novel details of construction and combinations of parts hereinafter more fully described and pointed out in the claims, it being understood that changes may be made in the construction and arrangement of parts without departing from the spirit of the invention as claimed.

Referring to the drawing Figure 1 is a bottom plan view of a bottom board equipped in accordance with the invention.

Figure 2 is a transverse section through said bottom board.

Figure 3 is an enlarged transverse section through one of the cleats and roller associated therewith.

Figure 4 is a transverse section through a modified form of cleat.

,Referringto thedrawing in detail, the refer-,

encgnumeral 5 designates generallya bottom board for a'm'old. In this connection, thepresent invention does not,relate to a special bottom effectively per rollers carried by the cleats. In this connection, reference may be had to my copending application, Serial Number 613,927, now abandoned, having reference to a bottom board for molds, and such a bottom board is admirably suited for attachment of cleats and rollers. Other forms of bottom boards, however, can as well be used, and

it is believed advisable to state only that the boards are preferably of metal material.

Spaced transversely of the bottom board 5 are the parallel cleats 6, these being readily fashioned, in the form of the invention illustrated in Figs. 1 to 3, from channel material. In any event,

the web or inner wall of the cleat 6 is fixedly secured in any suitable manner to the under side of the bottom board 5, and extending below the bottom board are the parallel side walls 1, the

lower or outer ends of which are formed with the out turned longitudinal flanges 8.

Opposed openings 9 are formed in the side walls 1, receiving the axles l0, which are prevented accidental separation from the cleats by means of the pins I l.

Mounted for rotation upon the axles [0 are the flanged rollers 12, adapted for rolling upon the tracks T. Tracks T, as will be understood, provide a conveyor line or mold track, so that the molds can be transferred from one location to another with speed and ease. are preferably ball bearing equipped, and to this end, there is provided adjacent each end of the axle the bushing l3, between which are interposed the spaced apart inner race members [4. Race members M are grooved for reception of the anti-friction elements I5, said elements being also received in grooves formed in the outer race members [6 that are secured to the inner surfaces of the outer portions of the rollers. Packing rings I! are interposed between the race members.

Referring to Fig. 4, a modified cleat construction is there illustrated including the opposed members l8. The longitudinal edges of each member are outwardly flanged as at 19 and 2i],

The rollers l2 r if j 2,521,660

members I8 is preferably fashioned in the same manner as the roller of the first form.

It may be noted that the lower ends of the cleats, as defined by the flanges 8 in the first form of the invention and the flanges 20 in the second form of the invention, are disposed lower than the lowermost portions of the rollers l2. As a result, when the mold is removed from the tracks T, it is permitted to rest directly upon the 4 surface, said side walls and flanges extending the length of the bottom board, and rollers carried by each cleat, the feet projecting below the rollers.

2. The combination, with a mold bottom board, of spaced parallel cleats, said cleats including longitudinal side walls set edgewise relative to said bottom board and extending the length of the bottom board, said side walls being rigidly flanges a'ordlaszthe case maybe; said-,flanges-r 10 andfpermanentlmsecuredzalongdzheirluppur edges defining feet; whereupon the molds :are readily: adapted for storage, pouring, or other operations.

Additionally, it is of importance to note that the":

side walls of the cleats, and the projecting lower, ends of the cleats, protect the rollers completely,

and this is of advantage in many, operations, as;

for example, when bottom boards are used on. squeezer machines, the pressure will-be applied 'to' the cleat side walls rather than to the rollers,

What is claimed is: 1.
